The strength of this specific tubing lies in its composition, which is stabilized with columbium to resist carbide precipitation. This means it maintains excellent corrosion resistance, particularly against intergranular attack, after exposure to high temperatures. Mechanically, it offers impressive tensile and yield strength, especially the 347H grade with its higher carbon content, ensuring it performs reliably under high-stress conditions and retains its structural integrity. This combination makes it a robust and dependable choice.
